Other sources may be the hepatic, left gastric, renal, suprarenal , or superior mesenteric arteries in about 8% of cases.
They have also been reported arising from a suprarenal , common iliac, or superior mesenteric artery.
More rarely, a gonadal can originate from a suprarenal , inferior phrenic, superior mesenteric, lumbar, common iliac, or internal iliac or inferior polar renal artery.
Unusual tributaries include the superior phrenic, gonadal, renal, and suprarenal veins.
In one case, both the inferior suprarenal and the middle suprarenal arteries supplied the anteromedial part of the organ.
